BER and SNR analysis of optical network-on-chip using WCDMA codes

Abstract

In this work, we propose a new architecture of Network-on-chip (NoC) system with WCDMA codes. A Bipolar CDMA code is used to provide a good system performance and to reduce MAI (Multiple Access Interference). Two structures of receiver are employed, while putting into consideration a thermal noise limitation. On one hand, it has proved, in this paper, that system performance can achieve a BER value less then -90dBm with an acceptable node number. On the other hand, system bandwidth can reach 16Gbit/s with an acceptable SNR compared to wired architecture.
